OF LEIPSIO, GERMANY.

MATERIAL FOR THE IVIANUFACTURE OF TRUNKS.`

SPECIFICATION forming part of Letters Patent No. 491,018, dated January31, 1893.

Application filed May 19, 18921 Serial No. 433,600. (No model.)

To all whom it may concern:

Be it known that I, ERNST PAUL KRENKEL, a subject of the King of Saxony,residing at Leipsic, Saxony, Germany, have invented certain new anduseful Improvements in Materials for the Manufacture of Trunks, 65o.;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of the specification.

This invention relates to an improved material to be used in themanufacture of trunks, chests, music instrument cases, dac.; my obj ectbeing to provide a material which will 'add stability and solidity tothe trunk, or upon whatever it is used.

With this object in view my invention consists in the peculiarities andcombinations of parts as will be more fully set forth and describedhereinafter and pointed out in the claim.

In the accompanying drawings: Figure 1 represents a longitudinal sectionof my invention. Fig. 2 represents a section taken on line x-x of Fig.1.

The reference let-terarepresents a strip or body portion ofWood,American poplar being preferably used, upon the upper face of whichis secured a sheet of canvas b forming the exposed face of the truuk orchest. For the purpose of preserving the same and keeping it waterproof,I cover it with a coat of oil paint, varnish, dac., which Will tend tomake it Wear Placed at intervals upon the upper surface of the Woodenplate ct, are halfround brace strips c, made preferably of rattan, orother fiexible material, running transversely to the grain of the Woodenbody portion a. These strips are glued to the plate a, and the canvasspread over them, it being also glued to the body portion, thus holdingthe three together. The under or opposite side of the body portion a iscovered with a layer of Manila or cocoa fiber d secured thereto by glue,and on this fiber is glued a layer of Chinese matting e, which gives aneat and finished appearance to the inside of the trunk. All theselayers are glued together, thereby forming a very solid body which Willbe tight, yet strong and durable. The staples f are driven through thematerial thus securely cemented together, and their ribs are bentlaterallyand thence backward into the surface of the matting, whichforms the interior covering. The ends are thus clinched to more securelyhold the staples in place and unite the layers of material more securelytogether. The ends of the staples being thus forced back into thematerial, prevent them from catching on objects that may be brought incontact therewith.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

A material for the manufacture of trunks or like articles, consisting ofa body portion of wood, half-round brace strips running transversely tothe grain of the body portion, an 'exterior covering of coarse materialplaced over said strips and body portion a iine fibrous material placedagainst the other side of the body portion, an interior lining ofmatting placed next to said fibrous material, and staples passing theWhole and distributed throughout, the inner ends being bent under andclinched, in the manner and for the purpose set forth.

In witness whereoflhave hereunto set my hand in presence of twowitnesses.

ERNST PAUL KRENKEL.
